It gets worse too:

It took me a long time to figure out what was wrong here, because each time I
looked into it I got so disgusted with autoconf that I gave up after an hour
or so.  Interesting that the problem occurs when you *disable* certain
features.

The answer is that certain essential autoconf tests (such as for EGREP) are
being done in the (sysloc.in) itcl.h if-else, which is being circumvented at
the command line by turning off tcl.  This seems to be a bug in autoconf
AFAIAC.  Fortunately there is an easy workaround.. to move some of the
essential system tests above the inclusion of sysloc.in.  I'll have it
committed shortly.
